Which term is defined as an explicit resource on which an access restriction is imposed?

• A. Subject
• B. Object
• C. Reference Monitor
• D. Operation

Answer: (A)

Access control focuses on protecting resources by attaching permissions to the resource itself. The explicit resource that carries the restrictions is the object—the file, database record, or other resource being protected. The subject is the user or process that requests access, not the resource being protected. The reference monitor is the mechanism that enforces the access control checks, and the operation is the specific action attempted (such as read or write). So the term defined as the explicit resource on which an access restriction is imposed is the object.
